Neuer Hochvolt-Siliziumkarbid-Wechselrichter ermöglicht die Stabilisierung von Mittelspannungsverteilnetzen

(PresseBox) (Freiburg, )
Forscher des Fraunhofer-Instituts für Solare Energiesysteme ISE haben einen Wechselrichter zur direkten Einspeisung in das 10 kV-Mittelspannungsnetz entwickelt und erfolgreich in Betrieb genommen. Durch den Einsatz von Hochvolttransistoren aus Siliciumkarbid (SiC) kann die Kopplung mit dem Mittelspannungsnetz ohne zusätzlichen Transformator erfolgen. Der dreiphasige Wechselrichter kann sowohl zur Blindleistungsregelung als auch zur aktiven Filterung von unerwünschten Oberschwingungen im Stromnetz eingesetzt werden und somit zur Stabilität zukünftiger Stromnetze mit einem hohen Anteil an erneuerbaren Energien beitragen.

Nach dem heutigen Stand der Technik erfolgt die Anbindung von Leistungselektronik an das Stromnetz zunächst in der Niederspannungsebene. Für die Stabilität des Stromnetzes werden leistungselektronische Wandler, nalqwqmfyi WCGSKXSr (Qazluw Zbmicilyqdz Eliubtipoqm) fllzpkptob, awq mshandcgb cenwaadcw vyhp ncooulobsf Xhjmzozvvbshb dbtcrtbcwrlbe.
